POKER OR BRANDlNG-TOOL FOR USE IN PYROGRAPHY.

SPECIFICATION forming part of Letters Patent No. 724,002, dated March31, 1903. Application filed October 5, 1900. Serial nasalsz. (No model-l1'0 alt whom it may concern:

Be it known that I, HERMANN FREYTAG, merchant, a subject of the King ofWiirtemberg, residing at Stuttgart, Kingdom of Wintemberg, GermanEmpire, have invented new and usefulImprovements in Pokers orBranding-Tools for Use in Pyrography, of which thefollowing is aspecification.

The present invention relates to an improved poker or branding=tool foruse in pyrography which is constructed in such a manner that the smoke,benzin vapors, and fumes largely developed during the operation areblown forward or away from the operator automatically and withoutcooling down the working point.

I will now proceed to describe my invention more fully, reference beinghad to the accompanying drawings, in which Figure 1 illustrates a viewof an apparatus complete as used in pyrography, Fig. 2 shows thereceiver of the poker 0r brandingtool on an enlarged'scale. Fig. 3illustrates a section on line A B, and Fig. 4' illustrates a centralvertical section through Fig. 2.

The end of the tube a is coupled to the flexible tube a of the benzinapparatus bin the well-known manner. Into the front end of the tube athe branding-tool receiver d is screwed, the poker or branding-tool ebeing inserted into the front end of this receiver (1. At the right andleft of the central bore h of the receiver 01 openings 1' 7c areprovided, which terminate in exhaust-holes f g externally of theoperating-tool e. The operating-tool e is hollow and provided withexhaust-openings Z m at its rear end. The tool e has one side shaped andsharpened like a knife, the other side being rounded.

When employing an operating-tool of the hereinbefore-described kind inthe art of pyrography, the air for blowing away the benzin-vapors isheated with said benzinvapors inside theglowihg-tool and escapes.through the openings Z m in the tool and through the openings f g atthe front of the receiver. In this manner the benzin-vapors are carriedaway automatically from the operator, on the one hand, and, on the otherhand, the tool is prevented from cooling down by virtue of blow-01fair-currents.

What I claim as new, and desire tosecure by Letters Patent, is

An improved poker or operating-tool for use in pyrography with a hollowoperatingpoint, knife-like sharpened at one side and rounded at theother side, exhaust-openings at the rear end of the hollowoperating-point and exhaust-openings at the front end of thetool-carrier communicating with the exhaustopenings at the rear end ofthe operatingpoint, substantially as described and shown and for thepurposes set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
